Retraction note to: J Mater Sci: Mater Electron (2017) 28:16397–16402https://doi.org/10.1007/s10854-017-7550-x


The Editor-in-Chief has retracted this article. After the publication of the article, concerns were raised regarding XRD patterns presented in Fig. 1. Further investigation by the publisher found evidence of attempts to manipulate the peer-review process. The authors failed to provide any explanation for the raised concerns.

The Editor-in-Chief therefore no longer has confidence in the data presented in this article.

None of the authors have responded to any correspondence from the editor/publisher about this retraction.
